The clean bench creates a local high - cleanliness environment in the operating area through a unique fan and filtration system. The outer shell is often treated with cold - rolled steel plate spraying, which is sturdy, durable, and aesthetically pleasing, and the workbench surface is made of corrosion - resistant and easy - to - clean materials. The fan draws in air, which is first preliminarily filtered by a pre - filter to remove large - particle impurities and then finely filtered by a high - efficiency filter. The clean air is sent into the work area in a laminar flow, effectively removing tiny particles and microorganisms. Its advantage lies in providing a stable and reliable clean environment, with simple operation and the ability to adjust the air speed and work area size according to needs. It is widely used in biological laboratories, pharmaceutical workshops, electronic assembly, and other places with high requirements for environmental cleanliness, providing clean protection for experimental operations or product production and preventing product contamination.
